I checked a few things out on my new (to me) 2005 VJ Campervan the other day and came across this under the floor:
It appears to have fuel lines going in and out, but they disappear over the top of the tank, and I wasn't easily able to trace where they went from there.
I have never seen anything like it before. What is it and what purpose does it serve, please?
Cheers,
Joe
